This invention relates to containers formed with a casing or body of fibrous material, such as paper board, and an inner liner bag of thin,

flexible material, such as cellophane, and more The invention consists in the novel featuresand in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had 20 to the accompanying drawings in which like characters designate corresponding parts in all the views. a

Figure 1 is a side, elevational view, partly in longitudinal section, of a container embodying 25 the invention.

Figure 2 is a fragmentary, elevational view of the upper end of the container previous to the sealing of the liner bag to its supporting member, and the sealing of the cover to the same.

30 Figure 3 is a fragmentary side elevational view of the upper portion of the container, with the liner bag and its supporting member partially removed from the casing, and the cover closure to be sealed to the bag supporting member.

35 Figure 4 is a view, similar to Figure 1, illustrating a modified form of structure.

Figure 5 is a view, similar to Figure 2, with the bag attached to its supporting member, and the top closure unattached.

40 Figure 6 is an enlarged, elevational view partly in section of the top portion of the container with the sealed liner bag removed.

The invention comprises generally, a container including a casing of fibrous material provided 45 with a suitable bottom closure, a ring member encircling the upper end of the casing and overlapping the upper edge thereof and being folded upon itself to form an upwardly facing channel, a bag of thin, flexible material arranged in the 50 casing with the open end of the bag extending into said channel and being secured thereto, and a top closure for the container secured at its periphery to the ring member.

The body or casing i0 is preferably formed of 55 fibrous material, such as heavy paper board, and

is provided with a bottom closure il secured to the casing in any suitable manner. As here shown, the bottom II is formed with a depending flange i1, and the lower end of the casing is crim'ped inwardly against the flange II, as 5 at 3.

In order that the containermay be suitable for use with liquid, or semi-liquid, products or those requiring a gas tight container, a bag ll of thin, flexible material is arranged in the cas- 10 lug II. The bag i4 may be formed of cellophane, or like material, which may have the qualities of being liquid and gas tight and preferably transparent.

The container herein referred to is of the type where the top closure is sealed to the bag, and the bag and top closure are removable as a unit from the casing in order that the contents of the bag may be inspected without unsealing the bag. With most materials, from which the bag ll maybe suitably made, it is difllcult to effect a proper seal between the open end of the bag and the top closure, ,ii the top closure is formed of the same or similar material, particularly where the container is to be used in connection with merchandise generating gases over pressure, such as coffee. It is also diflicult to effect such a seal between the bag wand a metallic top closure. It is well known that cellophane, and like materials, are exceedingly thin and accordingly, it is difficult to obtain a joint by crimping the cellophane and metal together which will withstand gas under pressure. The object of this invention is to overcome these difllculties, and

structure is provided for detachably supporting the bag in the casing l0, and by such structure the open end of the bag is conveniently secured 'ciosure which is sealed'to the metallicbag support in the conventional manner in which the top is secured .to an ordinary tin can.

The bag I is detachably supported in the easing "by a ring member designated generally at ii. The ring member Iiisfolded upon itself .to form upwardly facing channel, the inner side i6 fricticnally encircling the upper end of the casing M and being formed with an inwardly extending flange i1 overlapping the upper edge of the casing. The outer side ll of the channel extends upwardly beyond the plane of the flange l1, and is initially formed with a short radial flange I. The ring member 15 is formed with the outerside wall ll of the channel flaring outdepth of the channel, the open end of the bag.

is eflectively sealed thereto by bending or crimping in the outer wall i I and clamping the end of .o the-bag between it and the inner wall I, as indicatedto the left in Figure 1. v

The top closure for the container or bag may be metallic and in form general to the covers or top closures nowemployed to seal ordinary tin ll cans. The top closure consists of a discoidal portion 20 formed with an outwardly flaring marginal flange 2!. After the contents have been-placed in the bag il, the top closure is applied, and the flanges l9, 2!, are crimped to- D gether in the conventional manner, and as ill trated in Figure 1.. This effects a metal to me a1 seal between the closure and the bag or ring mex'nber i5. I

The ring member I5 acts as a supporting memher for the basil, and also as a means of retaining the bag in the casing during shipment,

' and until the bag filled. It also acts to stiflen the container and r'na'ke it more rigid. After the top closure is sealed to the outer side of the channel member, the bag ring menfber i5 and top closure may be. conveniently removed from the container, as illustrated in Figure 6, to permit inspection of the contentsof the bag, and during this operation the metallic ring member i5 and.

metallic top closure act as a rigid support for the h s.

In Figures 4 and .5, the ring member ibis v formed with a wider channel, with the inner and outer walls l6, l8, extending in parallel relationship. .In this structure, the open end of the bag I4 is secured in the channel by a wedge member 22 preferably of fibrous material, such as paper board.

With the structure shown in Figures 1 to 3, there may be instances where it is necessary to secure the open end of the bag in the channel by performing the crimping or bending operation previous to the insertion of the bag into the container. With the construction shown in Figures 4 and 5, the bag may be formed and inserted in the container with the open end of the bag extending over the channel. The wedge ring member 22 may be then pressed downwardly into the channel, drawing the open end of the bag with it anil sealing the open end of the bag in the channe What I claim is:
